I want to know the approximate value of a Natural Emerald with following features:
Carat : 12.31 //
Transparency: Transparent //
color: Light Green //
Cut: Oval Mixed Cut //
Measurement: 18.38 x 14.85 x 6.51 mm //
Refractive Index: 1.577 ~ 1.583
Its not really possible to give a quote on an emerald value by just a few specs without seeing its quality, luster, intensity and flaws. Only way to get a reliable value would be to bring it in to a respectable jeweler.
